5G-oriented Virtual Augmented Reality Scene Construction and Business Information Flow Demonstration

Aiming at the problems of large data volume, long calculation time, and information feedback speed in traditional virtual augmented reality-based scenes, this paper constructed a virtual augmented reality scene based on 5G technology. First, based on the research of camera models and related calibration techniques, this article discusses the coordinate conversion and registration between virtual scenes and real scenes in augmented reality systems based on natural feature points. Secondly, the control mechanism of data synchronization and transmission are realized by using 5G communication technology. Then, through the approximate nearest neighbour search of the descriptor, the feature points are quickly matched. Finally, by tracking the QR-code logo black frame, the global holography matrix virtual real registration method relative to the initial image is used to calculate the camera’s posture and the fast tracking registration of the scene is realized. The experimental results prove that the scene constructed in this paper has the characteristics of real-time, wide field of view, high immersion and flexible expansion, which not only meets the requirements of matching accuracy, but also has the advantages of small calculation amount and fast calculation speed, and has good robustness and real-time.
